Sounds like the delays are repeating one or two times fairly loud, decaying fairly quickly after that but remaining in the background for a few more repeats. Not sure if you can do exactly that with the DD7, but here is what I would do.

Use the tap tempo function to put in the songs tempo. Then all you need to change is level and feedback. I would put the level at maybe 11:00, and the feedback at between 12:00 and 14:00. I haven't actually used the DD7 but I used to own a DD3, and I have all the same parameters on my current Flashback X4 so hopefully this helps.

EDIT: dammit, a new post while I was updating I'll add them. I've been meaning to do a Get To The Choppa cover as well. Maybe I'll do it as well and we can compete Are you going to be doing the solos? I need to know what category to put each one (easy, intermediate, advanced).

Ahhh I really wanna get some kind of decent recording gear soon but I can't afford
I'd totally be up for doing something like One Armed Scissor by At the drive in! Would that song be classed as easy or intermediate?
